Cannot catch a feral kitten in my apartment to administer liquid medicine?

I recently (unfortunately) adopted three kittens. One loves people, the other is indifferent to scared, but doesn't mind being touched when she wants it. Then there's Fraidy. Walk within five feet and she tears off. I was able to catch her twice for a vet visit and one dose, only costing me some blood loss and skin loss. She is completey paranoid and although she has been around me for the same amount of time as the other kittens she refuses to get close. She will hiss, scratch, and puff up her tail. However, she needs the de-worming medication. Is there a better way to catch her or is there no hope?
